Can anyone help? Are numbers needed off the ecm to get the right base file to start with? Just trying to get this thing back to a stock baseline to try to sort out the smoke and lack of power down low. We are not looking to modify this truck past deletes and some tweaks for towing and economy. I have most recent efi live so I can't create a new file with deletes from a known good stock file at least that's my understanding. I'm assuming this means the tune is not an efi live file.so here's what I need: an unlocked stock 6.7l tune with dpf/egr deletes done. I tried to pull the file but I keep getting an error stating unknown format. Save the file prior to programming the ECM. ctz tune file open the tune file and: Navigate to F4: Properties -> Controller Information tab. Upon further inspection we found the dpf/ cat MIA and truck has no codes so obviously its been tuned. Once set, EFILive is UNABLE to correct this code and MIL, resulting in a dealer visit. Anyways it is a dog off the line and very smoky but comes to life in higher rpms but still smoky. performance mods: fleece 2nd gen manifold swap s463, built DTT trans, fass 150 lift pump, arp studs, efi live tuner, straight piped, intake, intake horn, 125hp nozzles, bag o parts cp3, fuel filter delete, boost fooler. He got it through his boss sight unseen to use as a tow rig for his work. I know others have had this problem but cant find a fix. I have efi live and have been tuning a few 5.9s but my brother just came into a 07 6.7l.
